"Hot Shot is a CA glue - cyanoacrylate.......I suggest trying it on an experimental piece before you commit to your rifle Jerry, just in case you don't like the results. "
I agree on trying out cyanoacrylate super glue before use. In past projects I have had super glue "haze" or "fog" the surrounding finish. The fumes can do it as well as the glue itself. I don't know the "whys" of this phenomenon, I just have seen it happen.
Just passing along a caution.
I also agree with Mike's note about staining the edges first, as stain won't take once the glue is on there.
